TECHNOLOGY:

• Women's Series is a collection of different styles of helmets, matches and prices created for women. While the level of detail and colour range is unique, these helmets do not have a unique "women's fit". This is due to the fact that there are no anatomical differences between the heads of women and men, except for the average size of the skull diameter. And since the sizes of Giro helmets cover 98% of the human population, we believe that the Women's Series offers more options for women than any other brand.

• Universal Fit Sizing - our Universal Fit helmets are sculpted to look good and fit everyone at the first fitting. By developing proprietary shell sizes based on specific customer groups and combining them with an easy to adjust fitting system, it's easy for you to choose the right size, straight from the box, without the hassle and cost of trying out multiple sizes.

• The Roc Loc Sport Fit System offers easy one-handed operation with a 7cm adjustment range. The feeling and sound of a click lets the rider know that the helmet can be adjusted to a comfortable size. With a similar comfort system to Roc Loc 5 and a "ponytail" space, the new Roc Loc Sport Fit System brings a premium feature to sports helmets.

The helmet does not have the MIPS system.
